BUG 1166: Fix JavaEmitter JVMUtil_NewDirectByteBufferCopy
Prevents jlong to jint truncation when capacity is passed from jni to java. com.jogamp.common.nio.Buffers newDirectByteBuffer and the underlying java.nio.ByteBuffer allocateDirect only work with capacitys of int size. Signed-off-by: Xerxes Rånby <[email protected]>
